Question

我想通过验证将.csv文件重要到数据库表。

我在添加用户表单上有一个函数add user，它对分机号码进行了验证，这是唯一的..

我还可以选择使用.csv文件添加批量用户。我可以添加用户但是如何为其添加验证，当我尝试上传带有用户详细信息的.csv文件时，它应显示错误extension is already used，但上传其他分机号码。

例如，如果.csv有100个用户，上传了80个用户，但由于他们的分机号码已经存在于数据库表中，因此没有上传20个用户，所以我希望这些20个用.csv文件导出。并显示错误。

我的模特是

我有一家公司，每家公司都有很多用户，每个用户都有唯一的分机号码。如果分机号码100分配给用户1，则无法将其分配给用户2。

我怎样才能做到这一点？任何建议，帮助一些代码。？感谢

通常，如果您在任何DataBase中使用Yii，您应该维护一个扩展ActiveQuery的Model类，如下所示：

<?php

namespace common\models;

use Yii;

class Profile extends \yii\db\ActiveRecord
{
public static function tableName()
{
    return 'TABLE_NAME';
}

public function rules()
{
    return [
        [['Phone', 'Email'], 'required'],
        [['Phone'], 'string', 'max' => 30],
        [['Email'], 'string', 'max' => 100],
    ];
}

public function attributeLabels()
{
    return [
        'Phone' => Yii::t('profile', 'Phone'),
        'Email' => Yii::t('profile', 'Email')
    ];
}

如您所见，您可以在return的{{1}}中声明您的验证规则。这里的示例中的那些非常简单，但是，存在许多其他内置验证器以及使用您自己的自定义验证器的能力，包括添加JS验证的可能性。您可以阅读更多相关信息here。

现在，当您使用模型时，您必须将数据加载到其中并验证它以便以后保存它。首先，在我看来，确保您的输入在PHP服务器上输入有效（在本例中为.csv文件）之前更正确，而不是从DataBase的验证引擎收到“硬错误” 。无论如何，为了将数据加载到模型中，我们首先需要将.csv作为字符串加载。为此，将.csv放入项目文件夹，例如function rules()

\common\models\file.csv

剩下的就是将<?php $csv = file_get_contents(Yii::getAlias('@app/common/models/').'file.csv'); $csvArray = str_getcsv($csv); $errorCsvArray = []; foreach ($csvArray as $newEntry) { $model = new \common\models\Profile(); if ($model->load($newEntry)) { $model->save(); } else { $errorCsvArray[] = $model->errors; } }转换为$errorCsvArray。这样做的一种方法是here。

此外，请注意.csv在填充模型之前也会验证。有关load()，load()，validate()和save()的更多内容，您可以找到here。

在我的Yii应用程序中也有员工导入。在该唯一字段中是员工代码。我的功能是，

 public function actionEmployeeimport() {
    $model = new ContactForm;
    if (isset($_POST['ContactForm'])) {
        $model->attributes = $_POST['ContactForm'];
        $uploadedFile = CUploadedFile::getInstance($model, 'filea');
        if ($uploadedFile == "") {
            Yii::app()->user->setFlash('error', 'Please select a file.');
        } else {
            $allowed = array('xlsx', 'xls');
            $filename = CUploadedFile::getInstance($model, 'filea');
            $ext = pathinfo($filename, PATHINFO_EXTENSION);
            if (!in_array($ext, $allowed)) {
                throw new CHttpException(404, 'File extension error. The allowed extension is xlsx.');
                exit(0);
            } else {

                $ext = end((explode(".", $uploadedFile)));
                $timezone = new DateTimeZone(Yii::app()->params['timezone']);
                $date = new DateTime();
                $date->setTimezone($timezone);
                $date = $date->format('dmYhis');
                $fileName = "{$date}.{$ext}";
                if (isset($uploadedFile)) {
                    $uploadedFile->saveAs(Yii::app()->basePath . '/../banner/' . $fileName);
                }
                //reading portion : here each column is read row and column wise; please check the sample
                //import file to get the column format. The heading row can be kept. The heading is ignored
                //while reading the excel or csv file.
